Abstract

The present invention provides a method and system for drying mineral slurry concentrate and high moisture content minerals using activated alumina. The method and system dries the mineral slurry concentrate by combining the slurry with the activated alumina. While in combination, the mixture is agitated to maximize surface contact between the activated alumina and the slurry. As the mineral slurry concentrate contacts the activated alumina, the surfactant moisture on the mineral elements is then absorbed by the activated alumina. The activated alumina allow for the water molecules to be adsorbed by the activate alumina, thus being removed from the slurry elements. After a period of agitation, the method and system thereby separates the activated alumina from the mineral slurry concentrate.
